I'm not sure. In my experience (back in the HID retrofit days) when an igniter or ballast has quit the bulbs don't light or do some other abnormal behavior like flickering. The bulbs are supplied 35w by the ballast and the high current by the igniter when lighting. If those fail... the bulbs do as well. I think that's the way it works, but hopefully someone more familiar with the electrics will chime in.
